I argue against several extant views (Rolston, etc) about the value of endangered species. I argue that the best way to defend a non-anthropocentric view about the value of endangered species is to appeal to the intrinsic value of biological diversity.

Synthetic organisms are at the same time organisms and artifacts. In this paper we aim to determine whether such entities have a good of their own, and so are candidates for being directly morally considerable. We argue that the good of non-sentient organisms is grounded in an etiological account of teleology, on which non-sentient organisms can come to be teleologically organized on the basis of their natural selection etiology. After defending this account of teleology, we argue that there are no (...) grounds for excluding synthetic organisms from having a good also grounded in their teleological organization. However, this comes at a cost; traditional artifacts will also be seen as having a good of their own. We defend this as the best solution to the puzzle about what to say about the good of synthetic organisms. (shrink)

I call for “postnaturalism” in environmental philosophy—for an environmental philosophy that no longer employs the concept nature. First, the term is too ambiguous and philosophically dangerous and, second, McKibben and others who argue that nature has already ended are probably right—except that perhaps nature has always already ended. Poststructuralism, environmental history, and recent science studies all point in the same direction: the world we inhabit is always already one transformed by human practices. Environmental questions are social and political ones, to (...) be answered by us and not by nature. Many will worry that this conclusion leads to environmentally pernicious consequences, and to problems of relativism and idealism, but I argue that it does not. Practices are real, not ideal, and not all practices are equal: those that acknowledge human responsibility for transforming the world are preferable to those that don’t. Environmental harm results when we do not recognize our own responsibility for the world our practices create. (shrink)

Biocentrists are criticized (1) for being biased in favor of the human species, (2) for basing their view on an ecology that is now widely challenged, and (3) for failing to reasonably distinguish the life that they claim has intrinsic value from the animate and inanimate things that they claim lack intrinsic value. In this paper, I show how biocentrism can be defended against these three criticisms, thus permitting biocentrists to justifiably appropriate the salutation, “Let the life force (or better (...) the ethical demands of life) be with you.”.

Maintaining the coherence of the distinction between nature and artefact has long been central to environmental thinking. By building genomes from scratch out of 'bio-bricks', synthetic biology promises to create biotic artefacts markedly different from anything created thus far in biotechnology. These new biotic artefacts depart from a core principle of Darwinian natural selection – descent through modification – leaving them with no causal connection to historical evolutionary processes. This departure from the core principle of Darwinism presents a challenge to (...) the normative foundation of a number of leading positions in environmental ethics. As a result, environmental ethicists with a commitment to the normative significance of the historical evolutionary process may see synthetic biology as a moral 'line in the sand'. (shrink)

Extinction is usually associated with the death of the last remaining individual of a species, taxon, or population of organisms. Here I ask the question of whether extinction might also be applied to cases where individuals of the relevant category remain alive. Global impacts in the Anthropocene suggest extinction may be broader than typically thought. Technologies available in the emerging ‘synthetic age’ alter taxa in ways that may appropriately be characterized as extinction. The core of the more traditional account of (...) extinction remains valuable. Losing the last few individuals of a taxon matters. But emerging types of loss may demand a broader understanding of extinction. This broader understanding could capture more of what humans are doing to the biosphere. (shrink)

The mass extinction visited upon us by capitalism involves many kinds of devastation. Here I clarify the grounds for assessing the most obvious of these harms, i.e., decimation of species diversity. The thesis that variety among species has intrinsic value motivates, and in turn follows from, the “variable value view” (VVV) of abundance within any given species. In contrast, standard axiologies have no place for the intrinsic value of species diversity. I show that the VVV provides a better justification than (...) the latter do, of the way in which a widely-used empirical indicator summarizes the overall state of life on Earth. These considerations favor ecocentric value theory – which ascribes intrinsic value to properties of ecological wholes, like species diversity, that do not supervene on the well-being of their constituent organisms – over its main competitors. I conclude by widening the focus from wild nature alone to the biosphere comprising both wilderness and the domesticated realm. This broadened perspective helps to link the science and ethics of biodiversity with the political struggle to extract ourselves from the moral abyss of mass extinction. (shrink)

Welfarism is the view that morality is centrally concerned with the welfare or well-being of individuals. The division between welfarist and non-welfarist approaches underlies many important disagreements in ethics, but welfarism is neither consistently defined nor well understood. I survey the philosophical work on welfarism, and I offer a suggestion about how the view can be characterized and how it can be embedded in various kinds of moral theory. I also identify welfarism's major rivals, and its major attractions and weaknesses.

How might human beings be called to exercise virtue, which is to say, modes of acknowledgement, humility, and discernment, in regard to the impending (no matter how distant chronologically) extinction of the human species? It is argued that the inevitable extinction of the human species be affirmed as a good, in spite of how daunting and uncanny this act might be. This affirmation is called for as humans struggle to find an ethical response appropriate to their creaturely existence, as well (...) as to their devastating complicity in a historical and geological moment of mass species extinction.

Concern for the fate of rare species leads us to ask why the extermination of species is wrong. No satisfactory account can be given in terms of animal rights, and a speciesist perspective can yield at best only a case for preservation of those species which enough people happen to care about. An attempt is made to analyze the concept of rarity, and its relation to value. Finally, it is suggested that the problem can be resolved only in terms of (...) an environmental ethic, according to which the existence of each species, and of ecological wholes, is held to have intrinsic value.
